The old server is trying to send, but I end up getting an undeliverable message saying no connection could be made. I know port 25 is open because I can telnet to it. I'm wondering if I'm missing something in my configuration. Can you take a look? Thank you.
Here are the active settings in /etc/postfix/master.cf: ... smtp inet n - y - - smtpd
This says port 25 is for smtpd and that's good.
And here are the setting I have in /etc/mailman3/mailman.cfg # /etc/mailman3/mailman.cfg
This is irrelevant as the message never gets to Mailman.

Here are the results from netstat:

And Postfix master process is listening on port 25.
You say you can telnet to port 25. Can you do that from the old MM 2.1
server? Can you connect and receive the greeting and send EHLO hostname and get a good response?
